A model rocket is launched directly upward at a speed of 28 meters per second from a height of 12 meters. The function f(t)=−4.9t^2+28t+12, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket hit the ground? Do not round until the final answer. Then round your answer to two decimal places.
